* Used to declare a structure unaligned, so that the C compiler,
* if necessary, generates code that doesn't assume alignment.
* This is required because there is no guarantee that the packet
* data we get from libpcap/WinPcap is properly aligned.
*
* This assumes that, for all compilers that support __attribute__:
*
* 1) they support __attribute__((packed));
*
* 2) for all instruction set architectures requiring strict
* alignment, declaring a structure with that attribute
* causes the compiler to generate code that handles
* misaligned 2-byte, 4-byte, and 8-byte integral
* quantities.
*
* It does not (yet) handle compilers where you can get the compiler
* to generate code of that sort by some other means.
*
* This is required in order to, for example, keep the compiler from
* generating, for
*
* if (bp->bp_htype == 1 && bp->bp_hlen == 6 && bp->bp_op == BOOTPREQUEST) {
*
* in print-bootp.c, code that loads the first 4-byte word of a
* "struct bootp", masking out the bp_hops field, and comparing the result
* against 0x01010600.
*
* Note: this also requires that padding be put into the structure,
* at least for compilers where it's implemented as __attribute__((packed)).
